Coupled-channel Omnès matrix for the $D$ -wave isoscalar $π π / K K ˉ$ system and its application to $J / ψ \to π^{0} π^{0} γ, K_{S} K_{S} γ$

Igor Danilkin, Oleksandra Deineka, Emilie Passemar +1

In this work, we construct the $D$ -wave isoscalar $π π / K K ˉ$ coupled-channel Omnès matrix, formulated to satisfy unitarity, analyticity, and the appropriate asymptotic behavior.…

A dispersive estimate of the $a_{0} (980)$ contribution to $(g - 2)_{μ}$

Oleksandra Deineka, Igor Danilkin, Marc Vanderhaeghen

A dispersive implementation of the $a_{0} (980)$ resonance to $(g - 2)_{μ}$ requires the knowledge of the double-virtual $S$ -wave $γ^{*} γ^{*} \to π η / K K (I = 1)$ amplitudes. To obtain these ampli…

Data-driven dispersive analysis of the $π π$ and $π K$ scattering

Igor Danilkin, Oleksandra Deineka, Marc Vanderhaeghen

We present a data-driven analysis of the resonant S-wave $π π \to π π$ and $π K \to π K$ reactions using the partial-wave dispersion relation. The contributions from the left-hand cuts…

The anomalous magnetic moment of the muon in the Standard Model

T. Aoyama, N. Asmussen, M. Benayoun +129

We review the present status of the Standard Model calculation of the anomalous magnetic moment of the muon. This is performed in a perturbative expansion in the fine-structure con…
